I am a huge Mary King fan. She is both a great ride and a class act. At age 11 Mary King decided she wanted to be a professional 3-day event rider. And now 40 years later she shows no signs of slowing down. King has ridden in five Olympics, she has won six team World and European Championship golds and four British Open titles. In this Olympics, she was part of the Silver Medal team and rode best dressage test to date on Imperial Cavalier.
Below is a link to a great interview.
